' Y Application filed August 29,' 1906. Serial No. 332,534.

Patented July 28, 1908. i

To allwhom 'it mai/mconcem: j 'Be it known that I, BERT W. PUNGHES, a citizen of the United States of America, re-

lsiding at Toledo, in the county of Lucas and more particular reference to the means for feeding the cartridges from the magazine into the barrel; and, further, the means for compelling the locking of the breech-block prior to the iring of the gun.

In the drawings,-Figure 1 is a side elevation of the frame of the gun, with one sideplate thereof broken away; Fig. 2 is a cross section; Fig. 3 is a sectional elevation, showing a portion of Fig. 2, with the parts in diff erent positions; Fig. 4 is a cross section on line os-x of Fig. 3 Fig. 5 is a view similar to arts; Fig. 6 is an elevation of a portion of 1g. 2, showing the breech-block unlocked; and Fig. 7 is a section on line y-y of Fig. 4, illustratingl the operation of the extractor.

The frame of the gun is preferably formed of an integral side-plate A and top-plate B, together with a detachable frontlate C.

.D is a breech-block longitudinally slidable within the frame and engaging suitable guides E on the frame.

F is the magazine, which is of segmental form and located in theforward portion of the frame, beneath the breech-block, into its closed position.

G is a follower within the magazine7 carp ried by a pivotal arm H, and adapted to feed a series of cartridges upward.

The breech-block D in normal position is locked by the engagement of its rear end with a shoulder a formed in the top-plate B of the frame. This shoulder is preferably formed by cutting away-the inner face of said topplate at b, so as to permit the breech-block to move upward therein, but a central rib c is left, which forms a guide for the cartridges The breech-block is grooved at d to receive this guide c.

l is a toggle lever7 which constitutes -both the actuating connection and the locking means for the breech-block. This lever comprises the members ef, the former being pivotedcat g inthe lower portion of the frame,-

and the latter being connected by a .swinging link J with the breech-block. .The pivot-pin K, which connects the member f with the link J, extends across the space within the frame, and into engagement withsegmental guide-ways 7 h in the front and rear plates of the frame. The central ivot or knuckle of the toggle is connected with a reciprocatory rod L, extending forward and provided with a suitable hand-operated actuating member (not shown). Thus,- the .movement of the rod L will cause the swinging of the tog le lever I about the pivot g, while the guide-s ots 7L h will determine the path of movement of the pin K and the angularity of the member f to the member e and link J. These guides h 71.l are so shaped that the member f and link `J are in substantial alinement during the vgreater part -of their travel, but after the breech-block has reached its forward position, a vertical movement of the pin K is permitted, so that a further movement of the to gle will strai hten the members e f thereo and force t e breech-block laterally into engagement with the lockingshoulder a.

M is a hammer which is in the form of a pivoted arm within the hollowl frame and preferably secured to the detachable plate C thereof.

N is the firing-pin slidably secured in the breech-block and extending rearward therefrom. The arrangement is such that the hammer will swing through substantially the samepath as that traversed by the toggle lever l, and will be actuated by thel latter during the retraction of the breech-block. This will cock the ha'mmer and engage it with the trigger mechanism (not shown), by which it may be subsequently released when the breech-block is in normal position. The hammer is under the tension of a suitable spring O, which will cause it to fly up and strike the projecting end of the firing-pin.

As has been stated, it is one object of the construction to avoid possibility of firing when the breech-block is unlocked.Y This is accomplished by providing the knuckle of the toggle lever l with a pin P, which projects into the path of the' hammer. This, as illustrated in Fig. 6, will prevent the hammer from contactingwith the firing pin so long as the members c f of the toggle are in `angular relation to each other, but, when the toggle is straightened to force the breechmer M and will prevent the firing of the gun g,

furthermore, the impact of t ie hammer against the pin P will of itself straighten the toggle, and thereby effect the locking of the breech-block.

Thecartridges are fed from the magazine F each time the breech-block is withdrawn into the space vacated thereby. To prevent the feeding of more than one cartridge into the path of the breech-block, a stop is provided which arrests the inward movement of the cartridge, and holds it until after the initial forward movement of the breechblock, which disengages the said cartridge from the stop and also intercepts the following cartridges, which are constantlyT pressed upward by the tension of the follower. This stop is preferably formed by the elements constituting the extractor', and comprising a lug i on the side-plate A of the frame, and

the coperating hook Q on the breech-block.`

The space between said lug and hook is slightly less than the diameter ofthe cartridge, so that the latter is prevented from passing into full alinement with the barrel until after the initial movement of the breechblock disengages it from the lug i. As soon as thus released, the tension of the follower, acting through the series of cartridges, will press the partly-engaged cartridge into exact alinement with the barrel, in which position it is held by the guide-rib c during the return of the breech-block. The forward movement of the breech-block required for disengaging the head of the cartridge from the lug 't is sul'licient to move the side of the breechblock into the path of the head of the following cartridge, so thatonly one cartridge at a time can be engaged with the breech-block.

What I claim as my invention is 1. In a un, the combination with a reciprocatory reeeh-block, of a magazine, a spring-pressed follower therein for feeding a series of cartridges from the magazine into the space vacated by said breech-block when retracted, and an extractor constituting a sto for-limiting the initial inward movement of t 1e foremost cartridge, for the purpose described.

2. In a gun, the combination with a reciprocatory breech-block, of a magazine, a s ring-pressed follower therein for feeding tie series of cartridges from the magazine into the space vacated by said breech-block when retracted, an extractor comprising a hook on said breech-block, and a stationary coperating lug, the said extractor and lug coperating to form a stop for limiting the initial inward movement of the foremost cartridge when the breech-block is completely retracted, and from which said cartridge is released upon the initial forward movement of the breech-block.

3. rl`he combination of a reciprocatory breech-block, a frame having a portion above the breech-block recessed in its under face for the reception of said block when in forward position, means actuated by the hammer in. its forward movement for forcing said block` into said recess, a magazine arranged beneath said block and recess, a follower for feeding a series of cartridges from said magazine upward and into the space vacated by the retraction of said block, and a guide-rib projecting downward in said recess and engaging a corresponding groove in said breechblock, said rib serving to aline the cartridge entering the space vacated by the breechblock with the barrel.

4. In a gun, the combination with a reciprocatory breech-block, of a frame member above said block recessed in its under face to receive and form a locking shoulder for said block when in forward position, a magazine beneath said block and recess, a follower for feeding the cartridges upward in said magazine and into the space vacated by the block upon the retraction thereof, a guide-rib projecting downward in said recess and engaging a corresponding groove in said breech block, said rib serving to aline the cartridges with the barrel.

5. In a gun, the combination with a reciprocatory breech-block, of a magazine, an extractor having a hook thereon and a stationary coperating lug, said extractor and lug being spaced from each other slightly less than the diameter of the cartridge and coperating to form a stop for limiting the initial inward movement of the foremost cartridge when the breech block is completely retracted.

6. In a gun, the combination witha reciprocatory breech-block, of a magazine, an extractor having a hook thereon, a stationary coperating lug, said extractor-hook situated on one side, the coperating lug on the frame on the opposite side of the breech-block and spaced from each other slightly less tha-n the diameter of the cartridge' and coperating to form a stop for limiting the initial inward movement of the foremost cartridge when the breech-block is completely retracted.

7. In a gun, the combination with a barrel and frame, of a breech-block mounted in said frame for longitudinal reciprocation, a shoulder on said frame with whlch the rear end of said breech-block engages in closed position, a toggle lever secured to said frame extending transversely of said breech-block and adapted when straightened to press the block into engagement With said shoulder, a less than the diametervof the cartridge and link connecting said toggle to said block7 a vcoperating to form a stop for limiting the firing pin, a hammer operating in a plane at the side ofthe toggle lever, a member on said toggle lever in the path of said hammer whereby the toggle lever is straightened and the breech-block locked before the operation of the firing pin.

8. In a gun, the combination With a reciprocatory breech block, of a magazine, an eX- tractor having a hook thereon, a stationary cooperating lug, said extractor and lug being spaced from eachother a distance slightly initial inward movement ofthe foremost cartridge 'When they breech block is completely retracted, the breech block upon its initial forward movement being adapted to disengage the cartridge from the stop.

In testimony whereof I affix my signature in presence of tWo Witnesses.
